Abstract
A shift register includes a latch clock generation circuit and a clock latch circuit. The latch clock generation circuit generates a latch clock signal and an inverted latch clock signal based on a first internal clock signal, a first inverted internal clock signal, a second internal clock signal, and a second inverted internal clock signal. The clock latch circuit latches a control signal in synchronization with one signal selected from the first internal clock signal, the first inverted internal clock signal, the second internal clock signal, and the second inverted internal clock signal. The clock latch circuit also latches the latched control signal in synchronization with the latch clock signal or the inverted latch clock signal to generate and output a shift control signal.
